By 2021 the F3 800 had become the sharp end of MV Agusta's three-cylinder line, and the RC versions in particular were built to be raced rather than admired. The ignition barrel survived every other revision. JP KS MV012 removes it across the whole 2021–2023 range, including the Rosso and the RR.
Key Features
- Covers F3 800, 800 R, 800 RC, 800 Rosso and 800 RR, 2021–2023
- Replaces the ignition block, barrel and key
- About 350 g saved from the steering head
- Machined Ergal housing, anodised black
- IP69K-rated push button
- Key Box included for the MV Agusta immobiliser
Five Variants, One Mounting
MV separates the F3 800 range by electronics, suspension and finish rather than by architecture, and the ignition mounting is common to all of it. That is why a single part number reaches from the base 800 to the RC. If you are moving between variants — and MV owners frequently do — the switch moves with you.
Not the 675
JetPrime lists a separate part for the F3 675 and the Ago 800. The 2012–2020 machines use a different ignition arrangement from the 2021-on 800s, and the two switches are not interchangeable. Check the model year before ordering; the shape of the bike will not tell you which side of the change it falls on.
Materials
Ergal is 7075 aluminium under its Italian trade name — the alloy used where a part must be light and still carry load. Machined from solid rather than cast, the housing keeps thin wall sections without losing stiffness, and there is no casting porosity to hold water. The anodised surface is integral to the metal, so it does not chip at the edges.
